This year marks a historical time for the American Chemical Society; the Celebration of the 25th Anniversary of the National Chemistry Week (NCW). The ACS Student Chapter of the University of Puerto Rico, R�o Piedras Campus coordinated various activities and also encouraged members' participation. NCW was of great enjoyment, but a lot of effort was needed from volunteers to ensure the success in each activity. More than one hundred students volunteer themselves, with their enthusiasm, support and commitment we were able to impact more than one thousand children of our beautiful island of Puerto Rico. Some of the activities that were presented are: A Green Chemistry Fashion Show, a Volunteers' Party, a Nanotechnology Conference, Mol Day Celebration, Open House, Chemical Demonstrations, Volunteers-Faculty Students Get Together and food donations.  The outcomes will be presented.
